It uses a 3D printed yoke to embrace the Z-slider. I had to drill and tap some M4 screws in the sides. I also had to work around the Z limit switch. @OnefinityCNC if you’re listening, some pre-drilled and tapped holes would help in future revisions!
My design supports different dust boot configurations. The top swivels and accepts a 4" hose. The tube is 80mm acrylic vs 4" to avoid interference with the Y feet or rails. The airflow is significantly improved. I used ESD filament and copper tape that, along with a wire-wound and grounded hose, cut the static down to nothing.
Clearance on the Gen2 to the front Y rail feet is very tight.
This limits your design options for accessories like this, for example, larger tube or shoe. For me, I would have taken the clearance over the little bit more of X travel. I’ve toyed with the idea of moving the X limit switch and shorting the X travel but so far, I’m living with the constraint.
Happy to share design files with anyone interested.
Nice design David. I ran into some issue with the dust show that sits and limits the Z-travel and been sorting different alternatives for hose channeling. I have the Gen 2 65mm spindle size with a 2.5" OD hose. Do you mind sharing the STL files tof the dust boost? I would like to build a similar set-up
Terrific solution! As I contemplate a Gen 2 machine, I was hoping there could be something that replicates the function of the SuckIt dust boot on my Shapeoko 3XL. I have a 3D printer and would also really appreciate you sharing the print files (and better yet, the STEP or f3d (Fusion?)) files if you are willing. Great work!
great and well done ,when u think about it ,and maybe im looking at you picks wrong its open where the spinal enters . the spindle pushes air down , wouldn’t think a lot would escape there add is th vacuum pulling from the side . very clever, great work, your a genius. (as long as it works as it looks hehe)
I made a version that provides 0.25 inch clearance, which reduces your X travel from 49 to 48.5. If you use this ensure you change the X travel in the controller config.
David’s mention of the Z limit switch workaround is key, and the ESD filament plus grounded hose setup is a practical detail. For the 2.5" hose, a swiveling top with an 80mm tube might need a reducer, but that should still improve airflow without increasing the outer profile. The tight clearance at the front Y rail feet means any shoe design has to stay compact. Sharing the STL files would let others test fit on the 65mm spindle.
